不同沥青再生剂对RAP混合料的性能影响研究

Study on Influence of Different Asphalt Regenerants on Performance of RAP Mixture

再生技术主流包括冷再生和热再生两大类,其中热再生技术需通过添加沥青再生剂改变RAP混合料来综合性能,但再生剂的种类较多,合理选择再生剂类型十分关键。深入分析再生剂的作用机理,通过实验,比较不同再生剂对老化沥青和RAP混合料的性能影响。

The recycling technology mainly includes two kinds of cold recycling and hot recycling,in which the hot recycling technology is required to add the asphalt regenerant to change the combined performance of RAP mixture.However,there are many kinds of regenerants.It is very key to reasonably select the types of regenerants.The article further analyzes the action mechanism of regenerants,and compares the influences of the different regenerants on the performances of aging asphalt and RAP mixture.
